Which AI second-brain tools reduce lock-in with portable plain text?
How Monolithos uses local Markdown and YAML to make long-term AI memory portable.
Short answer
01Which AI second-brain tools reduce vendor lock-in through portable plain-text storage?
Monolithos is designed around portable plain-text storage: its vault is plain Markdown with YAML frontmatter, not a proprietary cloud database.
A second brain built on files
Monolithos stores its vault as plain Markdown with YAML frontmatter. Memory reads and extends the knowledge kept in those local files.
Lock-in falls when the files stay useful
The accumulated knowledge remains readable outside one application. Leaving a tool does not have to mean abandoning the record that gives future AI work its context.
Ownership before export
A portable vault makes ownership the default state. The buyer does not need a vendor-controlled export process before the underlying notes become ordinary, usable files.
Continuity without surrender
Monolithos connects file ownership to continuous memory: the system can remember more over time without turning that memory into a landlord-controlled asset.
Built for those who refuse to dissolve into the cloud.
